cover. Forcibly removing the battery cover may bend or damage the key.
If the battery cover is frequently removed, the battery cover may become
loose.
When installing the battery, make sure to check the direction of the bat-
tery.
Installing the battery in the wrong direction may cause the battery to
deplete rapidly.

Trunk light
The trunk light turns on when the trunk is opened.
Trunk easy closer (vehicles with power trunk lid)
In the event that the trunk lid is left slightly open, the trunk easy closer will
automatically close it to the fully closed position.
Function to prevent the trunk being locked with the electronic key inside
When all doors are being locked, closing the trunk lid with the electronic
key left inside the trunk will sound an alarm.
In this case, the trunk lid can be opened pressing the trunk release button on
the trunk lid.
Even when the spare electronic key is put in the trunk with all the doors
locked, the key confinement prevention function can be activated so the
trunk can be opened. In order to prevent theft, take all electronic keys with
you when leaving the vehicle.
Even when the electronic key is put in the trunk with all the doors are
locked, the key may not be detected depending on the places and the sur-
rounding radio wave conditions. In this case, the key confinement preven-
tion function cannot be activated, causing the doors to lock when the trunk
is closed. Make sure to check where the key is before closing the trunk.
The key confinement prevention function cannot be activated if any one of
the doors is unlocked. In this case, open the trunk using the trunk opener.
Overload protection function (vehicles with power trunk lid)
The trunk lid will not operate when excessive load is present on the top of the
trunk lid.
Fall-down protection function (vehicles with power trunk lid)
While the trunk lid is opening automatically, applying excessive force to it
will stop the opening operation to prevent the trunk lid from rapidly falling
down.

CAUTION
Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in seri-
ous injury.
Remove any heavy loads, such as snow and ice, from the trunk lid before
opening it. Failure to do so may cause the trunk lid to suddenly shut again
after it is opened.
When opening or closing the trunk lid, thoroughly check to make sure the
surrounding area is safe.
If anyone is in the vicinity, make sure they are safe and let them know that
the trunk is about to open or close.
Use caution when opening or closing the trunk lid in windy weather as it
may move abruptly in strong wind.
Do not attach any accessories other than genuine Lexus parts to the trunk
lid. Such additional weight on the trunk lid may cause the lid to suddenly
shut again after it is opened.
The trunk lid may suddenly shut if it is
not opened fully. It is more difficult to
open or close the trunk lid on an incline
than on a level surface, so beware of the
trunk lid unexpectedly opening or clos-
ing by itself. Make sure that the trunk
lid is fully open and secure before using
the trunk.
When closing the trunk lid, take extra
care to prevent your fingers etc. from
being caught.
When closing the trunk lid, make sure
to press it lightly on its outer surface. If
the trunk grip is used to fully close the

CAUTION
Trunk easy closer (vehicles with power trunk lid)
Power trunk lid (if equipped)
Observe the following precautions when operating the power trunk lid.
Failure to do so may cause serious injury.
Check the safety of the surrounding area to make sure there are no obsta-
cles or anything that could cause any of your belongings to get caught.
If anyone is in the vicinity, make sure they are safe and let them know that
the trunk is about to open or close.
If the trunk closer switch is pressed while the trunk lid is opening during
automatic operation, the trunk lid stops opening. Take extra care when on
an incline, as the trunk lid may open or close suddenly.
On an incline, the trunk lid may suddenly shut after it opens automatically.
Make sure the trunk lid is fully open and secure before using the trunk.
In the following situations, the power trunk lid may detect an abnormality
and automatic operation may be stopped. In this case, the trunk lid has to
be operated manually. Take extra care in this situation, as the stopped
trunk lid may suddenly shut, causing an accident.
• When the trunk lid contacts an obstacle
• When the 12-volt battery voltage suddenly drops, such as when the
power switch is turned to ON mode or the hybrid system is started
during automatic operation
Do not attach any accessories other than genuine Lexus parts to the trunk
lid. The power trunk lid may not operate, causing itself to malfunction, or
the trunk lid may suddenly shut again after it is opened.
In the event that the trunk lid is left
slightly open, the trunk easy closer will
automatically close it to the fully closed
position. It takes several seconds before
the trunk easy closer begins to operate.
Be careful not to catch fingers or any-
thing else in the trunk lid, as this may
cause bone fractures or other serious

recall your preferred driving position.
Registering procedure
Record your driving position to button “1”, “2” or “3” before
performing the following:
Carry only the key you want to register, and then close the
driver’s door.

the seat and outside rear view mirrors will not move.
Turn the power switch to ACCESSORY mode or ON mode, or
fasten a seat belt.
The seat and steering wheel will move to the recorded position.
